I see this when I start a worker and then try to start it again forgetting it's already running (I don't use start-slaves, I start the slaves individually with start-slave.sh). All this is telling you is that there is already a running process on that machine. You can see it if you do a ps -aef|grep worker
you can look on the spark UI and see if your master shows this machine as connected to it already. If it doesn't, you might want to kill the worker process and restart it.
